Abstract

This paper deals with the relationship between possession of private vehicles and air quality, applying panel data model and based on the data in 31 provinces of China from 2003 to 2009. The research shows that there is hardly positive correlation between them in the provinces in China. On the contrary, the correlation between them is negative in most of the provinces. As a result, we conclude that private vehicles don’t cause serious air pollution and there must be other more essential factors that cause air pollution. Key words: Possession of private vehicles; Air quality; Panel data model
